HandBrake is a software application that can convert MPEG video (including DVD-Video) into a MPEG-4 video file in .mp4, .avi, .ogm, or .mkv containers. It supported any DVD-like source: VIDEO_TS folder, DVD image or real DVD (unencrypted--protection methods including CSS are not supported internally and must be handled externally with third-party software and libraries), and some .VOB and .TS files
